Tính năng sản phẩm
The Series RHP-E/N Wall Mount Humidity/Temperature/Dew Point Transmitters
are the most versatile room transmitter on the market. The stylish housing is well
vented to provide air flow across the sensor to improve measurement accuracy. The
humidity and the dew point are measured using a capacitive polymer sensor. The
humidity and dew point can have either a current or voltage output, while the optional
temperature output can be a current, voltage, RTD or thermistor. For models with
current or voltage for the temperature output, the temperature range is field selectable.
BENEFITS/FEATURES
• Reduced installation cost with combined humidity/dew point and temperature
sensing
• Wide application environments from a large selection of temperature sensors and
2% and 3% accuracies
• Reduced inventory with field selectable output
APPLICATIONS
• Air economizers
• Room comfort monitoring
• Greenhouse monitoring
